A MALWARE ANALYSIS AND ARTIFACT CAPTURE TOOL A dissertation submitted to Dakota State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Cyber Operations March 2019 By Dallas Wright Dissertation Committee: Dr. Wayne Pauli Dr. Josh Stroschein Dr. Jun Liu ii iii Abstract Malware authors attempt to obfuscate and hide their execution objectives in their program’s static and dynamic states. This paper provides a novel approach to aid analysis by introducing a malware analysis tool which is quick to set up and use with respect to other existing tools. The tool allows for the intercepting and capturing of malware artifacts while providing dynamic control of process flow. Capturing malware artifacts allows an analyst to more quickly and comprehensively understand malware behavior and obfuscation techniques and doing so interactively allows multiple code paths to be explored. The faster that malware can be analyzed the quicker the systems and data compromised by it can be determined and its infection stopped. This research proposes an instantiation of an interactive malware analysis and artifact capture tool. iv Declaration I hereby certify that this dissertation constitutes my own product, that where the language of others is set forth, quotation marks so indicate, and that appropriate credit is given where I have used the language, ideas, expressions or writings of another.

  • What Are Kernel-Mode Rootkits?
    www.it-ebooks.info Hacking Exposed™ Malware & Rootkits Reviews “Accessible but not dumbed-down, this latest addition to the Hacking Exposed series is a stellar example of why this series remains one of the best-selling security franchises out there. System administrators and Average Joe computer users alike need to come to grips with the sophistication and stealth of modern malware, and this book calmly and clearly explains the threat.” —Brian Krebs, Reporter for The Washington Post and author of the Security Fix Blog “A harrowing guide to where the bad guys hide, and how you can find them.” —Dan Kaminsky, Director of Penetration Testing, IOActive, Inc. “The authors tackle malware, a deep and diverse issue in computer security, with common terms and relevant examples. Malware is a cold deadly tool in hacking; the authors address it openly, showing its capabilities with direct technical insight. The result is a good read that moves quickly, filling in the gaps even for the knowledgeable reader.” —Christopher Jordan, VP, Threat Intelligence, McAfee; Principal Investigator to DHS Botnet Research “Remember the end-of-semester review sessions where the instructor would go over everything from the whole term in just enough detail so you would understand all the key points, but also leave you with enough references to dig deeper where you wanted? Hacking Exposed Malware & Rootkits resembles this! A top-notch reference for novices and security professionals alike, this book provides just enough detail to explain the topics being presented, but not too much to dissuade those new to security.” —LTC Ron Dodge, U.S.
